#109446 - Wrong Approach ? Responding to: ???'s previous message |
All the examples above do indeed use |=
the issue I have is how to simply fill the rightmost 4 bits with 1's, actually I suppose I could do this Mask >> 4bits ~Mask Mask << 4 bits ~mask That would be pretty clever, I'll have to give it a go Marshall [edit] On reflection this then leaves me with the left most 4bits as 0's so perhaps not a good idea either Marshall |

| why not just |= bits_to_be_added | 01/01/70 00:00 | |

| Try an Array | 01/01/70 00:00 | |
| |= 2^RightMostBits -1; // sure? | 01/01/70 00:00 | |
| You are correct about ^ != pow() | 01/01/70 00:00 | |
